seems like the show won a special thread for peeps like us to discuss about it here
i got obessed with the show because of the maturity of the content; the anime address many ethnics problems that we are powerless to dealt with and the brotherly love between the 2 main characters
i would agree that they could inject some female char to accompany them but that will be a very sad case for the little brother ...
(I hope he cant get any worser other than the tin suit)
